Creative Sensor Mounting When Flexible Couplings Limit Space.
By Steve Gordon
In this situation, there is little or no room to mount the laser sensors to the motor and pump. What would you do? You could remove the entire coupling and do an “uncoupled alignment”. Or, be creative…
Remove ½ the flexible coupling. Then mount the M sensor on the motor shaft and the S sensor on the exposed coupling hub of the pump.
The key is to mount the sensors to surfaces that will give you accurate and repeatable measurement results. By keeping ½ the flexible coupling in place you will eliminate any coupling backlash. Now go about the business of checking and correcting any misalignment.
